ANTICREEPER..

Specification of Letters Patent.

Patented. March 16, 1909'.

Application led November 16, ISDE. Serial No. 462,820.

l 'device of that kind which is designed to prevent what is known as creeping or longitudinal movement of the lrail to which it is applied.

. .i lt'is a weil known .fact that the tendency of railway rails to cree is particularly noticeable on double tracii lines where the trains all run in one direction and is especially troublesome on grades. Theattempts usually made tn overcome this movement consist chiefly in ap lying a ,clamp to the foot flange of the raii; the clamp being provided with a foot to abut against the adjacent tie, so that when the rai tends to creep, the tie receives the, pressure through the foot. Various objections are made to this form of anti-Creeper, chief ameno` which is that the jaws of the clamp soon relax, thereby allowing the rail to creep as before.

The present invention aims to overcome this defect by providing a construction which will tend to become. tighter through use.

`\"`i"ith these andA other objects nr view, as will more fullyT hereinafter app ear, the present invention consists in certain novel details of construction and arrangement of arts, hereinafter fully described, illustrated 1n the accompanying drawings, and more particularlyl pointed out in the appended claims,

it being understood that variousichanges in the form, proportion, size and minor details of the device maybe made without departing from the spirit or sacrificing any of the advantages of the invention.

in the accompanvlng drawlngs forming a part of this specliicatlonr-Figure l 1s a horizontal sectlon taken through a rail showing my device in longitudinal section and applied to the rail. a view ofthe stay. Fig. 3 is a detailed perspective of the wedge.- Fig. 4 is a horizontal section of the stay.

V 4Similar numerals of reference are employed to designatel corresponding parts throughout.

Fig. 2 is a perspectivev The stay comprises avbody portion adapted to lie across the lower face of the foot ilange of the rail,v and provided at one end with an upturned hook to engage th edge thereof, and at its opposite end providedwith any abutment and -a seat in which is fitted a sliding gripping memberl or Wedge to bite the opposite side of the foot flange when creeping occurs. The stay is preferably formed of a single piece of metal-provided on one face with strengthening ribs 1. The length of the stay is considerably greater than the widthof the ordinary foot ian'ge 2 of.' the rail and terminates at one end in an u turned hook 3 which engages one edge of t e`foot ilange 2. The upper faceof the stayis flat and adjacent the end remote from the hook 3-is provided with a transverseseat -or depression 4 and a vertical post 5,

posed at the end of the stay vopposite to the hook 3. The inner face of the (post 5 is provided with a convex surface, an on its upper end is secured a hook or overhang 6 similar to the hook 3, but of greater length than the 'iattenits inner edge lying substantially ina 'vertical plane with the inner edge of the seatV 4. The distance between the lower face of the overhang-6 and the upper face .of the iioor 4 is considerablyA greater than the thickness at the outer edge of the foot Harige ofan ordinary rail, and the distance between the highest point in the convex surface of the post 5 and the engaging surface of the hook 3@ 1s considerably greater than the width of the rail lfoot flange, so that when the device is applied and the hook 3 engages one-side of the foot'flange, as shown in Fig. 1, a socket will be formed by the opposite side of the foot flange and inner face of the post 5. The

'form of wedge employed to enter the socket consists of a single piece of metal substantially semicircular in shape and provided on its base with a concave recess 7 eccentrically disposed with respect to the short axis of the wedge, and of a size to straddle the convex surface of the post 5. Thus it can be seen that a wedge has been formed provided with comparatively wide and narrow ends S and 9. The upper and lower faces of the wedge are [lat and coincident with the upper face is a projecting lip 10. The distancey between the lower face of the wedge and lower/face of the lip 1() is such that the said lov'er face of the lip, will,.,when the wedge has been inserted within the seat 4; bear-on the upper face of the foot Harigey 2,

Coincident with the lower face of the Wedge is a second lip 11, considerably less in Width than the upper lip 10, and designed to bear between the upper and lower lips, will tend to bite the edge of the foot flange when the latter tends to force it to move in one direction. Formed on the outer face of the stay and having its upper end coincident with the floor of the seat 4 is a depending foot 7 adapted to bear on the sidevof the cros's tie toprevent the stay from` vcreeping with the rai In the use of the device, the stay is applied to the lower face of the rail until the hook' 3 engages one side of the foot flange thereof 5 into the socket now formed by the` opposite 'side of the foot flange'and convexsurface .of the post 5, thefnarrowend of the wedge is inserted until the convex surface between the upper and lower lips bears on the edge of the foot flange. This will leave the larger p ortionand widened end of the Wedge projecting beyond the side of the stay. `With a suitable tool the wedge may be given the initial ti htening. i

By re erring now to Fig. 3, it will be seen that the wedge is provided with a series of vertifal openings 1 2 adjacent its narrow end and when the operation just described has been completed, a suitable piigor the like may' be inserted through one of these openings, so that its ends will bear on one side of the wedge andoverhang 6. to prevent backward movement of the wedge. When of the rail to creep will force the widened portion ofthe wedge tu enter the socket,

thus forcing the vconvex side of the wedge to bite tighter and maintain the rail in proper osition. Y

What is claimed is l. An anti-Creeper for rails comprising a body having at one end a hook to engage one side of the foot flange of a rail and a vertical post at its opposite end, a depending foot adjacent said post, and an arcuate wedge having one side adapted to bear on said verrthe parts are in this position, the tendency4 tical post and its opposite side to engage the flange of the rail. v i

2. An anti-Creeper for rails comprising a body having at one end a hook lso-engage one side 'of the base flange of a rail, and a vertical post having a convex surface at the opposite end of said body, a depending foot adjacent said, post,l and an arcuate wedge having a concave socket topengage the convex surface .of-said post, andfurther provided with a convexsurface to engage the flange of the rail.

3. An. anti-cree er for rails comprising a body having a rai u engaging hook at vone end thereof and provided at the other end with a seat, a vertical post provided with a co'nvex surface disposed at the outer end of said seat,

a depending foot on said body portion, andV a wedge provided with an eccentric depression on one s1de to ,bear on tlieconvex surface of said post, and further provided on its opposite side with a surface to bear 'on the foot flange of the rail.

4, An antl-creeper for rails comprising aV body portion-havin a hook at one end to engage one side of t e foot flange of a rail,

and provided on its opplosite end with a vert a convex surface, a l
